Hey everyone, since the next call looks very focused on rules, David Cox and I put together some data on the rules being run nationwide. We looked at 118 different LO206 classes (every one we could find data on) to come up with some recommended rule sets for maximum commonality: http://kartrank.com/lo206-data

There is a lot of data there so I’ll copy the short version here:

Briggs LO206 Masters
There are not enough Masters classes (only 5 nationwide) to make a recommendation. Of the classes that exist the rules were in line with LO206 Senior (except age), so there does not seem to be a compelling reason to offer a Masters class separate from Senior.
